OpenAI Node - "msearch() is not a valid tool, select another one"

[n8-builder-dude]

N8N OpenAI Node

I am communicating with OpenAI GPT-40-mini model via OpenAI Node – Message Assistant operation. Generally, this works fine, but I have been running into issues as executions have increased.

tools attached: (see workflow nodes at bottom of post)

• google calendar tool
• custom code node to generate a date/time string using today’s date/time
• add user context pulls data from Google Sheets

– OpenAI Thread with error

msearch() error messages

When I view the Thread run logs in OpenAI platform dashboard (platform.openai.com/threads) I see a common theme: an error message:

msearch(
{"queries": ["Christmas break", "Winter holiday schedule"]})
Dec 17, 2024, 9:14 AM
msearch is not a valid tool, try another one.

If I run the same set of questions via the OpenAI API playground (platform.openai.com/playground/assistants) the assistant replies without any of the msearch() errors.

I am wondering if this is related to n8n’s usage of Langchain? Or something else? Please help!

Can’t say I have Is msearch one fo the tools. you’re defining? Could you please share the full workflow so that I can reproduce this locally?

@oleg

Is msearch one fo the tools. you’re defining?

Answer: No, it is not.

See below for the n8n OpenAI node where I call OpenAI Assistant API.
I am still unable to figure out where msearch() is referenced…

My OpenAI node has three tools:

1. google calendar,
2. code node,
3. execute workflow node.

Here is my Assistant configuration:

• custom system prompt (can share privately if you’d like to see the prompt)
• gpt-4o-mini,
• file_search tool enabled,
• attached OpenAI Vector store,
• response format=text.

additional_run_context function definition:

google_calendar function definition:

get_current_time_date_time:

Any update or thoughts on why I am seeing this issue with msearch() ?
